Shackle Flip and Block question???????????

OK, I ordered my 4" ORD shackle flip yesterday and it's suppose to set my Pinion angle correct. Question I have is, I'm going to run a 2" block with this , but does it need to be a tapered block or a non tapered block?????

I have 4" ORD shackle flip + 3" Tuff Country springs for the rear of my K5. I didn't want too have any blocks. I went with a extra inch back there because of the extra weight that K5's and burbs have that pick ups don't. I'd reather sit slightly higher in the rear then front.

I was wondering the same thing, because when i pick up my d60 and 14b i plan on doing an ord shackle flip, and figured id just throw 2" blocks until I can afford new TC springs.(my buddy owns a machine shop)

For my two cents again, read my above post. But if you're in doubt I have a solution for you. Mock it up with some flat wood blocks and check your pinion angle. If it's good get flat blocks, If you need correction one way or the other get the tapered and run them in which ever direction you need to.

Also here's a quote from ORD

"Pinion angle is a popular question with this kit. The quick and easy answer is that there is no quick and easy answer. Proper pinion angle depends on drivetrain length, wheelbase, gears, tires, vehicle speed and more. It usually boils down to what works for your truck. In general, the shackle flip sets the pinion angle about right for most 4" to 6" lift Blazers and shortbeds, especially the later models with the aluminum transfer cases. Longbeds and Suburbans will probably (but not always) need to shim the pinion down a few degrees for minimum vibration"

Yeah like Rhuara31 said it depends on what you are running. For example a 10blt or a 14bolt the pinion angles differ. Then your tranny and tcase setup! I am just going to do a mock up with 2x4s to see what will work best!
